Pin Insulator

Porcelain Versus Polymer Insulator:

Depending on the application, it may be more prudent to choose either a Porcelain Pin Insulator or a polymer insulator. Please use the charts below to compare the different types of insulators:

Porcelain Insulator Advantages Porcelain Insulator Disadvantages
  • Very long life, made of inorganic materials and do not age.
  • Very reliable, with a proven track record. Over 80 years of experience
  • Have higher leakage distance profiles
  • Easier to maintain, can be coated and washed
  • Have more flexibility in length with more units
  • Easy to identify a damaged unit
  • Strong in compression
  • Heavy, leading to more expensive shipping and more difficult handling
  • Could have hidden defects that are hard to detect
  • Vandalism is common from thrown rocks, or from being shot at
  • Pin erosion, and coupling hardware corrosion
  • Cement growth cracking
  • Weaker in tension

  • Polymer Insulator Advantages Polymer Insulator Disadvantages
  • Lighter in weight, almost a 90% weight reduction. This weight reduction leads to easier handling, reduced shipping and installation costs.
  • Better performance in high contamination areas
  • Overall better handling of shock loads
  • More aesthetically pleasing the eye, and smaller profile
  • More resistant to vandalism and breakage due to the forgiving nature of polymer
  • Strong in tension
  • More susceptible to damage from arcing or flash overs
  • Less experience in the field, still changing as more polymer products come out
  • Harder to check for inconsistencies or damages
  • Dimensions vary
  • Storage concerns
  • Dry arc distance is lower
  • Interface bonding issues
  • Weaker in compression
